We characterise the bolus insulin input which minimises maximum plasma glucose concentration predicted by Magdelaine and Bergman minimal models in response to any positive bounded disturbance whilst remaining above a fixed lower concentration. This characterisation is terms of maxima minima limits controllability such systems. Any further attempt will result hypoglycaemia.

Flaws due to race conditions in which the binding of a name to an object changes between repeated references occur in many programs. We examine one type of this flaw in the UNIX operating system, and describe a semantic method for detecting possible instances of this problem. We present the results of one such analysis in which a previously undiscovered race condition flaw was found.

Abstract In this paper we propose a set of algorithms that can automatically detect the use AES and recover both encryption key plaintext, assuming control code flow encrypting program, e.g., when an application is performing without user’s permission. The first algorithm makes fact monitor accesses to S-Box deduce desired data from these accesses; approach suitable software-based implementatio...
